So recently, I’ve noticed a lot of teams switching to a new design of robot that uses two arms (one on the front and one on the back) such as team 323V, 323S, and 100A. I’m just interested what advantage (if any) this gives the teams (a lot of the teams who changes to this design have great skills scores).
like you noticed, it’s really good for skills. lets you place two goals on the platform in a row without needing to do any funky dropping and switching.
can be nice in certain match situations too, but mostly a skills thing I think.
I’m assuming the arms are used for mobile goals, and if so:
As mobile goals can be worth a lot of points, teams are making their robots carry as many mobile goals are possible. There is a team I know that can pick up 3, but I think their original intention was 4-5. An easy way of getting more mobile goals is to replicate the pick up mechanism on another part of the robot, such as the back. This means they can pick up two at once instead of just one.
I am not familiar with those teams’ robots. Is what you are talking about similar to 1469A’s new reveal?
IIRC 11495E (mid school) has had this design since December
edit: December 4 https://youtu.be/VpaUIVsU8H0?t=1h41m15s and they won skills at that tornament. They were also tournament champion at a more recent tournament when allianced with a shopping cart.
I can see how it could benefit the skills score by allowing the team to just turn around rather than dropping the back goal, but I feel it could also be a detriment in that it would be more difficult to drive. The driver would have to know which buttons go to each arm and claw really well, otherwise would risk losing time.
No, the design is not quite the same as 1469A’s. At least not as when I last saw their robot.
Another team that uses this design is 98548A, Robotnerds (they have their reveal on VEX Forum).
Its great for skills, and if it parks on the platform and raises both arms it gives more room for the alliance to stack under. However, it does need alot of practice since you’ll have to move both arms and drive at the same time
Moving the arms and the drive should not be to much of an issue. For me the issue with these designs is that you can’t have a 6motor drive if you want to do rings unless you do some sort of motor sharing system and as mentioned above I think the biggest advantage of these bots is in skils not as much of a difference teamwork.
sounds like a skill issue to me.
You can learn fast, but it’s initially difficult pressing so many buttons at once
I’m not sure how the other teams with this design do this, but if I were to do this, I’d have one arm be a toggle switch with only an high/low option, with the other arm having using the right/left buttons and allowing it to move to any degree in between. The other buttons I would use for a conveyor belt.
Yeah, I’m interested how the teams with the two-arm design configure their remote.
Not sure about other teams, and also it would vary for each robot. We have our main (front) arm which is just a 4 bar with a claw on it, and a claw on the back that just drags mobile goals. We have L1 and L2 control the lift, R1 and R2 controlling the front claw, and the X and B buttons controlling the back claw.
So your team probably uses a controller scuff.
Not yet, im waiting for the new one that can press all eight buttons that @Pat.Chet.02 is making to come out.
Hello, I am Part of 11495E. The advantages of having this, is speed. It grabs two goals, stacks them and we just made adjustments, and it can climb now.
I am part of 11495e, and the dual lifts are quite easy to maneuver. We also have a great driver who practices almost every day.
